Abstract

Abstract : Nickel(0)-NHC nanoparticles bearing cinnamyl moieties catalyse effectively ( Z )-selective semi-hydrogenations. Abstract : Nickel(0) nanoparticles coordinated to NHC ligands bearing N-coordinated cinnamyl moieties were readily prepared by reduction of a [NiCpBr(NHC-cinnamyl)] complex with methyl magnesium bromide. The combination of a strong σ-donor NHC ligand with a π-coordinating appended cinnamyl moiety likely prevents nickel(0) nanoparticle aggregation to larger inactive species, and allows the effective and ( Z )-selective semi-hydrogenation of alkynes and ynamides.
